Adam Sweeting “Chris Squire obituary” http://www.theguardian.com/music/2015/jun/29/chris-squire
Squire’s favourite instrument was a 1964 Rickenbacker bass guitar, which he played throughout his career. It helped to mould his agile, melodic sound and gave it a cutting tone that ensured that it was prominent in the group’s sound, particularly so since Squire often played in a higher register than many rock bassists. This reflected the influence of one of his idols, John Entwistle of the Who. “I developed that trebly bass thing a little further,” said Squire, who would visit the Marquee club, London, weekly in the mid-60s to see the Who play.
